I found in my CD library collection The Andrew Lloyd Webber Musical Sunset Boulevard which I bought many years ago.
There is an old movie by the same title from 1950 which I found on the Internet Archive website

I started searching for the full video of the musical, but apparently they don't produce musical shows like with operas.
There is a very low quality full version on YouTube with Glen Close which looks like someone recorded it during a live performance without permission. Yet YouTube allowed it to be uploaded.

My question is if The Andrew Lloyd Webber musicals were ever released for streaming in high quality and if I can find a better quality version to the one I linked above.
Thanks for your comments.
